I cannot upgrade Ubuntu Gnome 16.04.3 to 17.04. I have switched the setting in Software & Updates to Notify me of a new Ubuntu version: For any new version, I also tried editing /etc/update-manager/release-upgrades
and verified that Prompt=normal
was indeed set.
I run
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
then
sudo do-release-upgrade -d
but it always returns:
sudo do-release-upgrade
Checking for a new Ubuntu release
Upgrades to the development release are only
available from the latest supported release.
This is not a duplicate of the previous question; the path for Ubuntu GNOME is 16.04.3 to 17.04. There is no 16.10 release of Ubuntu GNOME, so I'm not skipping any release versions.
16.04
-->16.10
-->17.04
